Novel PDC drill bit utilizing impact effect for improving heart rock breaking efficiency

The invention belongs to the field of technical equipment used in oil and natural gas drilling engineering, mine exploiting, geological drilling, constructional engineering, tunnel engineering, shielding and non-excavation, and relates to a novel PDC drill bit utilizing the impact effect for improving heart rock breaking efficiency. The PDC drill bit solves the problems that in the drilling process, a center rock column left in the center part influences drilling efficiency, and the position deviating from the center of a well hole shakes left and right. According to the technical scheme, the upper end of a turbine is fixed through a nut, the lower end of the turbine is fixed through a boss on a turbine shaft, an upper cam is connected to the turbine shaft through threads, a lower cam is fixed to a punch hammer through a sunk screw, the upper section of the punch hammer is hollow, a pore passage enabling drilling fluid to flow out is formed in the upper end of a shell on the lower portion, a pressing head with the top end provided with a tip-shaped PDC tooth is added to the tail end of a connecting cavity, as a main impact part, the lower end of the punch hammer becomes thin, and a bi-directional thrust ball bearing is placed at the lower end. The equipment enables the heart to generate longitudinal impact, improves the rock breaking efficiency and reduces drilling cost.

Distributed type non-slippage optical fiber strain sensor and manufacturing method thereof

A distributed no-slippage optical fiber stain sensor and a manufacturing method thereof are a distributed no-slippage Brillouin scattering optical fiber which is used for the health detection and monitoring of the structural facility and the manufacturing method thereof. The invention is characterized in that the sensor uses an UV resin signle mode fiber as a substrate, and a single mode bare fiber part which is eliminated with an UV resin coating layer is provided thereon. The exterior part of the bare fiber is provided with a basalt fiber packaging layer to form an optical fiber strain sensor. To the total adhibition packaging mode, the exterior part is immersed with epoxy resin and is packaged. To the fixed-point adhibition packaging optical fiber, a sleeve pipe is provided outside the bare optical fiber. A certain space is preserved between the sleeve pipes. The bare fiber between the sleeve pipes and the sleeve pipes are fixed on the immersed basalt fiber through the epoxy resin. The distributed no-slippage optical fiber sensor of the invention has high precision and high sensitivity. The long-distance and large-area structural stain information can be accurately obtained, and the manufacturing method is simple and easy.

Disc cutter trimming mechanism of sheet extrusion machine

The invention discloses a disc cutter trimming mechanism of a sheet extrusion machine. The mechanism comprises a lower disc cutter, a first rotating shaft, an upper cutter base, an upper cutter base positioning mechanism, an upper disc cutter, a second rotating shaft, a lower cutter base and a lower cutter base positioning mechanism, and is characterized in that an upper cutter acceleration mechanism is mounted on the upper cutter base, wherein a sheet following ring drives the upper disc cutter to rotate through a gear acceleration mechanism; and the gear acceleration mechanism enables the rotating linear velocity of the upper disc cutter to be quicker than the rotating linear velocity of the lower disc cutter. Compared with the prior art, the mechanism has the following beneficial effects: as the upper cutter acceleration mechanism is arranged, sheets are pulled to effectively drive the lower cutter and the upper cutter to rotate, the rotating linear velocity of the upper cutter is quicker than the passing linear velocity of the sheets, and the cutting of the cutter is facilitated; and the mechanism is simple in structure and excellent in use effect, effectively eliminates the slip phenomenon, and prevents the condition of incapability of cutting off the sheets due to no rotation of the upper cutter.
